Argon Laser Trabeculoplasty (ALT)

Argon Laser Trabeculoplasty (ALT)

An ophthalmologist at Fraser Eye Care Center and the Eye Care Center of Port Huron may recommend Argon Laser Trabeculoplasty, or ALT, as treatment for Glaucoma, particularly for Open-Angle Glaucoma. As technology has advanced, this form of laser surgery has become increasingly popular as an alternative to medication and traditional Glaucoma Filtration Surgery.

ALT is helpful in causing some areas of the eye’s drainage to shrink, allowing more room for fluid to drain faster. This reduces pressure within the eye that could cause damage to the optic nerve and loss of vision. The procedure requires no injections or needles and takes approximately 10-15 minutes once the patient’s eye has been completely prepared for the procedure. There is no pain during the procedure. Patients often experience seeing flashes of bright green or red light during the procedure, as the laser beam of light is reflected into the eye, and mild soreness and/or swelling inside the eye. Most patients resume normal activities within a few days.

Serious complications with ALT are extremely rare, but like any surgical procedure, it does have some risks. Our experienced doctors and staff have minimized these risks, and are prepared to discuss ALT and other treatment choices for patients with Glaucoma.
